✦ Synopsis
Raman and infrared spectra of 2-aminobenzotrifluoride, in the liquid phase, and single vibronic level fluorescence (SVLF) spectra, in a supersonic jet, have been recorded and assigned to give an almost complete set of fundamental vibration wavenumbers in (S_{0}). In the SVLF spectrum, the assignment of the (l_{2}^{0}) band, where (\nu_{1}) is the (\mathrm{NH}{2})-inversion vibration, is not so straightforward as for 3 - and 4-aminobenzotrifluoride, and the most likely assignment is discussed. The fluorescence excitation spectrum gives some lower vibrational wavenumbers in the (S{1}) electronic state and shows a long progression in the (\mathrm{CF}_{3}) torsional mode.
